Although the monsoons effect most part of India, the amount of rainfall varies from heavy to scanty on different parts. There is great regional and temporal variation in the distribution of rainfall. Over 80% of the annual rainfall is received in the four rainy months of June to September. The average annual rainfall is about 125 cm, but it has great spatial variations. This lead to excess rainfall in one region which results the flood and water shortage in other region which leads to the drought in other region. The interlinking project are envisaged with aim to transfer the water from the water surplus region the water deficit region. The Ponnaiyar (Nedungal Anicut) - Palar Intra-state Link Project of Tamil Nadu envisages diversion of 99 Mm3 of flood water of Ponnaiyar river available at Krishnagiri dam to the Palar River. The main objective of the link Project is to improve the Groundwater potential to stabilize the existing command area and stabilize the enroute command areas of Tamil Nadu state. The geotechnical investigation for the proposed Ponnaiyar (Nedungal Anicut) - Palar Intra-state Link Project was undertaken by CSMRS. The paper presents the soil investigations carried out along the canal alignment of the proposed link canal.

I. INTRODUCTION India is a vast country and is highly diversified in terms of natural resources and socio-economic setup. Moreover, its water resources are unevenly distributed in space and time. With increasing population and increasing aspiration Volume 8 Issue 1 – February 2017 380 ISSN: 2319 - 1058 International Journal of Innovations in Engineering and Technology (IJIET) http://dx.doi.org/10.21172/ijiet.81.052 for improved standard of living, there is an acute pressure on the demand and availability of water. In India, the river-linking project in a sensible and scientific manner will not only allow the prevention of the colossal wastage of a vitally important natural resource, flood and inundation by detaining flowing surface water of rainy seasons, but also ensure availability of water to drier areas, combating both flood and drought simultaneously. Moreover, it will generate 34,000 MW of hydropower and irrigation to an additional 35 million hectares (135,135 square miles) of land (Sharon Gourdji, Carrie Knowlton & Kobi Platt). II. INTERLINKING OF RIVERS IN INDIA Human societies have always tried to expand the spatial extent of availability of water by the diversion of streams or rivers. The idea of drawing water from the rivers in eastern India, which have larger run-off, in comparison to certain places in the peninsular region, where the precipitation levels are much lower, can be seen as an extension of that practice. The country receives about 4,000 cu km of water as precipitation annually. However, unlike the precipitation patterns in the temperate regions of the world, precipitation in India is characterized by acute variations in both space and time. A large part of the total precipitation on the country is received in the Himalayan catchments of the Ganga and Brahmaputra rivers. The distribution of precipitation over India is predominantly governed by the Monsoon, as a result of which the northeastern quarter of the country receives substantially larger precipitation, in comparison with the northwestern, western and southern parts. Though the west-flowing rivers originating from the Western Ghats have substantial runoff, the spatial scope for their wider utilization is limited (Upali A. Amarasinghe et.al). For assessing the water resources of India, the area of the country has been divided in 24 river-basins in which the west flowing rivers from the Western Ghats have all been clubbed as one. On the basis of the National Perspective on water resource development, the interlinking project has two components - the Himalayan and the Peninsular (NWDA web site). The Himalayan component includes construction of storage dams on the main tributaries of Ganga and Brahmaputra to transfer 'surplus' water to the west. The Peninsular component involves connecting rivers like Godavari and Mahanadi that have 'surplus' water with rivers like Krishna and Cauvery. A total of 31 link are envisaged, out of which 14 links will be in the Himalayan component and 17 links will be in the Peninsular component (Figure 1). III. PONNAIYAR - PALAR INTRA STATE LINK CANAL PROJECT The Ponnaiyar (Nedungal Anicut) - Palar Intra-State Link Project, Tamil Nadu envisages diversion of 99 Mm3 of flood flows/spill waters of Ponnaiyar river available at Krishnagiri dam from the existing Nedungal Anicut, located at 16 km downstream of Krishnagiri Dam, to the Palar River. The main objective of the link canal project is to improve the groundwater potential for stabilizing the existing command area up to 9500 ha. which is presently irrigated through open wells and bore wells in water-short Vaniyambadi taluk of Vellore district in Palar basin and feeding enroute system of water tanks (Eris) for stabilising the enroute command areas in Krishnagiri and Vellore districts of Tamil Nadu state. Apart the above, a quantum of about 3.882 Mm3 of water is planned for domestic water supply to enroute villages of 1.52 lakh population. The Ponnaiyar (Nedungal Anicut ) – Palar Link Canal off-takes from the left bank of the existing Nedungal Anicut at FSL 434.450 m and outfalls at 419.666 m into Kal Ar of Godd Ar, which is a tributary of Palar river near Natrampalli village of Vaniyambadi taluk. The total length of the link canal is 54.15 km. The canal passes by gravity through Pochampalli & Krishnagiri taluks of Krishnagiri district and Tirupattur taluk of Vellore district of Tamil Nadu. The canal is designed as unlined canal with trapezoidal section to carry the designed discharge of 68 cumecs with a uniform bed width of 25.0 m and full supply depth of 2.45 m. Uniform bed slope of 1:4500 is adopted for the entire length of the link canal. The link canal crosses 62 CD/CM structures enroute including one head regulator at off-take point and one out-fall structure at tail end. The main features and cross drainage structures along the canal alignment of proposed Ponnaiyar (Nedungal Anicut) - Palar Intra State Link Canal Project, Tamil Nadu are given in Table 1 a & 1 b.

BENEFITS FROM THE PROJECT The Ponnaiyar (NedungalAnicut) - Palar Intra-state Link Project of Tamil Nadu is planned as a multipurpose project with flood control, water supply and irrigation benefit in the downstream of Krisnagiri dam. The project is planned to divert the 99 Mm3 of flood flows/spill waters of Ponnaiyar river available at Krishnagiri dam at 50% dependability from the existing Nedungal Anicut, located at 16 km downstream of Krishnagiri Dam, to the Palar River (CSMRS 2015). The project will improve the groundwater potential and will stabilize the existing command area to an extent of 9500 ha which is presently being irrigated through open wells and bore wells in water-short Vaniyambadi taluk of Vellore district in Palar basin apart from feeding enroute system water tanks (Eris) for stabilizing the enroute command areas in Krishnagiri and Vellore districts of Tamil Nadu state. A quantum of about 3.882 Mm3 of water is planned for domestic water supply to enroute villages for about 1.52 lakh population.

    1 Issues Pertaining to Peninsular Rivers Wing Interstate Matters: (A) Mullaperiyar Dam Issue 1. on 29-10-1886, a Lease In

    Issues pertaining to Peninsular Rivers wing i. Interstate matters: (a) Mullaperiyar Dam Issue 1. On 29‐10‐1886, a lease indenture for 999 years was made between Maharaja of Travancore and Secretary of State for India for Periyar irrigation works. By another agreement in 1970, Tamil Nadu was permitted to generate power also. The Mullaperiyar Dam was constructed during 1887‐1895. Its full reservoir level is 152 ft and it provides water through a tunnel to Vaigai basin in Tamil Nadu for irrigation benefits in 68558 ha area. 2. In 1979, reports appeared in Kerala Press about damage to Periyar Dam. On 25th November, 1979 Chairman, CWC held meeting with the officers of Irrigation and Electricity, Deptt. of Kerala and PWD of Tamil Nadu and some emergency medium term measures and long‐term measures for strengthening of Periyar Dam were decided. A second meeting under the Chairmanship of Chairman, CWC was held on 29th April 1980 and it was opined that after the completion of emergency and medium term measures, the water level in the reservoir can be raised up to 145 ft. 3. The matter became sub‐judice with several petitions. On the directions of the Supreme Court in its order dated 28.4.2000, Minister (WR) convened the Inter‐State meeting on 19.5.2000 and as decided in the meeting, an Expert Committee under Member (D&R), CWC with representatives from both States was constituted in June 2000 to study the safety of the dam. The Committee in its report of March, 2001 opined that with the strengthening measures implemented, the water level can be raised from 136 ft.

    Need to Ensure Adequate Availability of Water in Palar River in Tamil Nadu and Also Expedite Pennayar - Palar Link Canal Project

    an> Title: Need to ensure adequate availability of water in Palar River in Tamil Nadu and also expedite Pennayar - Palar Link Canal Project. SHRI B. SENGUTTUVAN (VELLORE): River Palar, an inter-State river, originating in Karnataka, runs to a distance of 53 kms in Karnataka, 30 kms in Andhra Pradesh and 222 kms in Tamil Nadu. The river is covered under Schedule-A of the Madras-Mysore Agreement. As per Clause II of Agreement upstream State cannot construct any dam or reservoir without consent of the downstream State. During the monsoons, where adequate rainfall is received, the waters of the river replenish more than one thousand tanks, ponds and lakes on either side of its banks, which are the sources of water of drinking and irrigation in Vellore and Kancheepuram Districts. The Palar ayacut supports cultivation of roughly 4.2 lakh acres of lands. However, due to the construction of Check-dams across the river by neighbouring States of Karnataka and Andhra Pradesh, the water flow in the river has completely ceased leaving the land patched, dry and drought-stricken. To compound the problems, the Andhra Pradesh Government is raising the height of check dam in Perumpallam village on the very border of Tamil Nadu State to a height of 12 feet and more with a view to converting it into a reservoir. This would seriously impede water flow in the Palar and deprive Tamil Nadu of the much needed Palar water. In order to protect the ayacutdars, the inter-state Palar River has to be nationalised removing all dams and barriers constructed across it and the 52 km long Pennayar-Palar Link Canal Project has to be implemented expeditiously.

    The Chennai Water Crisis: Insufficient Rainwater Or Suboptimal Harnessing of Runoff?

    GENERAL ARTICLES The Chennai Water Crisis: Insufficient rainwater or suboptimal harnessing of runoff? Sumant Nigam*, Alfredo Ruiz-Barradas and Agniv Sengupta Chennai experienced acute water shortage during 2019 summer, and four years prior, an early- winter deluge. Analysis of 116 years (1901–2016) of rainfall in Chennai Sub-basin shows a weak climate change signal: Winter monsoon rainfall, has slightly increased, especially in December. The much larger Cauvery basin to the south also exhibits a nondescript climate change signal in winter rainfall. Late summer (September) rainfall in the Cauvery Basin has, however, precipitously declined in recent years (1987–2016). We show that this decline, as well as the mid-20th century increase, are attributable to natural multidecadal climate variability (Atlantic Multidecadal Oscil- lation) – cautioning against cavalier attributions of recent-period trends and the Chennai Water Crisis to climate change. Analysis of runoff – the rainwater leftover after its hydrologic and atmos- pheric processing – shows that harnessing even half of the winter monsoon runoff in the Chennai Sub-basin can satiate the city’s water demand for about seven months; and without needing new reservoir facilities.
